All our Deco models can work together. Under some circumstances, we have more than one Deco models (Deco M5, Deco M9 Plus, etc.) in hand and want to use them together in one network topology.

Q1: What to do if I want to set up a Powerline Backhaul network?

1. If you have more than 2 Deco P7 or Deco P9 units and want a Powerline backhaul network, please choose Deco P7 or P9 as the main Deco. And the powerline connection will be established only between Deco powerline products.

2. It is not recommended to choose Deco M4R/E4R as the main Deco if you have higher priority models.

Q2: How to set up different Deco models together for optimal performance without considering Powerline Backhaul?

There are two situations and it is recommended to do as follows:

1. When creating a new Deco network

Choose a main Deco in the priority order below, then follow the instruction in the Deco app to set it up.

After the main Deco is configured successfully, follow the instruction in the Deco app to add the slave Deco one by one.

2. When adding a new Deco to an existing Deco network

For example, you have set up a Deco M5 network already, but want to add a new M9 Plus into the existing mesh network to extend your wireless coverage.

In this case, it’s recommended to re-select M9 Plus as the main Deco to ensure the system performance. (Similarly, we recommend to follow the priority order when re-selecting the main Deco: Deco X60>Deco X20>Deco M9 Plus/Deco P7 > Deco M5 > Deco P9 > Deco M4R/Deco S4 > Deco E4R)

Take “add Deco M9 Plus into the existing M5 network” as an example. Please follow the steps below.

1. Update your Deco app

Go to the App Store or Google Play Store, check and update your Deco app to the latest version.

Note: When building a Deco network with different models, some features will disappear if one of the Deco units doesn’t support them. For example, if Deco M5 supports Fast Roaming while Deco M3W does not, then the Fast Roaming feature will disappear if you add the M3W unit into the M5 network. But don’t worry, these features will be added in future firmware updates.
